    Subject[PATCH 8/8] perf, tool: Add support to specify pmu style event
    Date
    Added new event rule to the event definition grammar:

    event_def: event_pmu |
    ...
    event_pmu: PE_NAME '/' event_config '/'

    Using this rule, event could be now specified like:
    cpu/config=1,config1=2,config2=3/u

    where pmu name 'cpu' is looked up via following path:
    ${sysfs_mount}/bus/event_source/devices/${pmu}

    and config options are bound to the pmu's format definiton:
    ${sysfs_mount}/bus/event_source/devices/${pmu}/format

    The hardcoded config options still stays and have precedence
    over any format field defined with same name.
